650i or 680i?

[Aivas47a]

I meant to add to my prior post, based on testing with one sample each of the Asus P5N32-E SLI (680i) vs. P5N32-E SLI PLUS (a modified 650), I found the overclocking on the two boards to be about the same, but found the Plus mobo to be more stable. (Probably related to that, the 650 chipset runs cooler at comparable voltages.)

The Plus board even has two 16x PCIe lanes, though as harmattan notes that does not really seem to be all that important in real world performance vs. two 8x lanes.
